This is part two to grinding the crankshaft, which again shows quite a bit of the setup required behind the scenes in order to grind a crankshaft! Aside from a bit of setup changes, the main journals are really relatively simple compared to the rod journals.

I'm in my late 60's and my father is long gone now. What I would have given to have a working relationship as you two are blessed with. Peace

@paulmace7910 2 года назад

These two videos are my favorites. I don’t care how long they are, I’m interested in see ing how it’s done. Your Dad obviously understands the process well and is excellent at explaining. Thank you. More like this please.

Well, that was just plain awesome. I've been told that my dad was a crankshaft specialist back in the '50s and '60s. Working for drag racers, and racing teams. This video shows what kind of machinist skills you need to be a specialist. Thanks

I Love you guys videos, I’m 56, when I was in my early 30s I worked in a machine job that built a lot of race engines. They pretty much turned me loose on the stock stuff. Surfacing heads, single angle valve jobs. Disassembly and reassembly. I love watching the more technical stuff that I never did. Thanks for the videos.I would have loved to work with and learn from your dad.

Just got another job at a machine shop this week and they asked me to start grinding crankshafts, which I've never done, so this helped me out. I'm running a berco rtm 270 and it appears to be very similar to yours except it's wore out and the diamond to dress the wheel is practically gone.

@samrodian919 2 года назад

Then the management are fucking stingy and will blame you for any fuck ups instead of putting some investment into new small parts like the diamond dresser. I'd look for a better machine shop to work for real soon because if you are a good machinist you won't be happy working there.

@Single_Phase 2 года назад

@@samrodian919 Yea the owner is in his 80's and has blamed me for a few random things already. Hopefully, he retires soon and his son takes over. The newest piece of equiptment is 40 years old. Cleaning takes forever because we have vats, pressure washer (it's supposed to be a steam cleaner but doesn't heat the water), wire wheels, and a blast cabinet. I hope I can talk someone into getting better equiptment. Me and my coworker talked about trying to get them to upgrade.

@leinadalan 2 года назад

There is a lot of importance that is involved with that radius, filet, cheek etc. Be cool if he talked about that. When I went to school for automotive machinist, I ground a 400sbc to fit in a 350sbc. Machine was huge. Good old Kirk Betts, very knowledgeable teacher. I've sense bought a scat crank for my stroker, but still have the old rods and crank. Prob always keep it. Was a very fun education to learn. The first time I saw him straighten a crank with a chisel and 5lb mall I thought it was a joke!!

@Allworldsk1 2 года назад

@robertunderwood6788 Год назад

I had a grinder wheel disintegrate while I surfacing a bearing sleeve many years ago. Being so close to the machine and things happening so fast I did not see where the pieces flew to. I leaned to the left reaching for the power button as a chunk flew by where my head used to be. Lucky to be alive. Another machinist just happened to be watching me from a few feet away and saw that chunk fly by my head and it scared him so bad he took the rest of the day off. My boss told me to go home too. I haven’t thought about that in so long but it came back when he mentioned the suicide wheel, the one that broke on me was narrow also.

@stevenr5911 2 года назад

It's always great watching a master at work. I am a machinist by trade and love building engines as a hobby but I have never been around crank grinding and always thought it would be fascinating to learn. Dad makes it seem so easy but as a machinist I completely understand how complicated and tedious it really must be but he just does it with ease and confidence.Thanks for the great videos.

@samrodian919 2 года назад

I could watch you dad working that crank grinding machine for days on end. He is so methodical in his approach and he is teaching you as he goes even though you are not touching the machine. When you come to grind your first crank he will be there with you correcting any mistakes you may or may not make given the tutorials you have had already. Go find a trash crank on a Sunday and get your dad to put you through your paces. You can practice to your hearts content in 5 thou increments! Lol

@albertgaspar627 2 года назад

I used to work with a kid who's dad was a Marine sniper who retired into the aeronautical machining industry. Poor kid grew up with "everything has to be perfect or don't bother" shadow over him :) Got a chance to help him learn that life has a lot of grey area and that certain jobs we did were "good enough" to leave time for the tasks that really did need more attention...or he'd still be there getting everything done one way only.

@dougderby9454 Год назад

Was fortunate enough to have a machine shop I used for 22 years. They had been in business over 52 years in the same location. Crankshaft specialist worked there 39 years. He did hundreds of cranks for me. Owner passed on and family liquidated. Not fun trying to find a reputable shop and machinist.

@randalljames1 Год назад

what really sux is how fast a shop like this is becoming more and more rare.. I started in the auto repair biz in Denver in 1976.. That shop is still there (Emick auto service) on the same property and still family owned... I learned a lot in those early days...

@bobolulu7615 2 года назад

After looking at some of the measurement checks thats done here, I wonder how many so-called 'professional' machine shops go to the same trouble as seen here. From those seal surfaces to the mains, a couple of thou here and there might be ok for your shopping basket runner, but not for a decent performance engine. Bravo.

Seeing this for the first time since I am building a 400 and using these videos to help. My crank was used in a $200. Core. Before I ground it it was only out .0008. using stock rods with arp bolts, stock crank .010 / .010 and .060 flat top forged Pistons. Doing. 6x-4 heads with stainless valves. 1.65 roller rockers and a ram4 camshaft. This is goin in a 1985 El Camino with a th350 with a shift kit and the 7.5 stock rear I added 3.73s and a posi outta monte ss. This should get goin quickly

@warbirdwf 2 года назад

Customer asking you why it costs so much to regrind his crank. Your response "watch this video".. It's pretty surprising to me, how much time it takes to just set up the machine and then dial in the crank before the sparks start flying 😳 I had no idea. This video series was very educational in regards to seeing what's involved. Is there an average time it typically takes to grind the the entire crankshaft from start to finish? Again, well done with the video and explanations.

@88SC 2 года назад

Question about the indexes that allow you to clock the crank pins to center. They appear to have detents (I noticed on the last grinding video), which I assume are for 90° and 120° divisions. That’s enough for nearly all automotive crankshafts. What do you do for the odd split journal job or five cylinder, if you get them at all?
